What should you check before buying a Santa Ana rental?

You’re buying a Santa Ana rental, or you’ve just closed, and need to know what rent you can charge and what paperwork comes next.

For covered units, the cap from September 1, 2026 through August 31, 2027 is $2.87 for every $100 of current rent, once per 12 months. No rent increase takes effect unless registration is complete and accurate.

This guide is educational, not legal or tax advice.

Does the rent cap apply to the building you’re buying?

The cap applies to residential structures built on or before February 1, 1995, except units expressly exempt under state law.

The City of Santa Ana’s Rent Stabilization and Just Cause Eviction Ordinance page also covers mobilehome parks established before 1990, regardless of ownership. Start with the building’s year built, then check the claimed exemption.

The city’s Property Activity Tool provides year-built information. If that information isn’t available, contact [email protected] or call (714) 667-2209.

Keep rent stabilization coverage separate from just cause coverage. Just cause has its own exemptions, including housing produced in the last 15 years and deed-restricted affordable housing. Those exemptions must be applied for and approved through the Rental Registry.

Rules differ from city to city: Anaheim has a planned intake program for state tenant protection issues, and Carson’s recent renters item produced no new ordinance.

How much can rent go up through August 2027?

For covered units, the maximum increase is $2.87 for every $100 of current rent from September 1, 2026 through August 31, 2027. The city announced this cap in its June 2026 Rent Stabilization Newsletter.

Only one rent increase is allowed in a 12-month period. Check the date of the last increase alongside its amount.

The Ordinance uses the lower of $3 for every $100 of current rent or four fifths of the change in the Consumer Price Index. The current cap uses the index change from May 2025 through May 2026. The previous cap, covering September 1, 2025 through August 31, 2026, was $2.42 for every $100.

Owners must give written notice of the Ordinance and tenants’ rights at the start of a lease or with any rent increase notice. It must use the language used to negotiate the tenancy. The city posts notices in English, Spanish, Vietnamese, Chinese, Tagalog and Korean.

What does the Rental Registry require each year?

Every rental unit needs annual registration or an official claim for an applicable exemption.

The Rental Registry page identifies the current program cycle as July 1, 2026 through June 30, 2027, with a July 1, 2026 filing deadline. Exemption claims are annual too. Until the city officially approves an exemption, it treats the unit as subject to the Ordinance.

The registration fee was $100 per unit from June 1 through July 31, 2026, then rose to $104 on August 1. Late penalties began October 1 and rise in monthly steps through June 30, 2027. An OC Independent editorial, an opinion piece, criticized the fee increase alongside the rent cap.

The city no longer mails invoices. The Tolemi portal generates the invoice when registration is submitted.

Owners who register and pay on time may pass through up to half the fee in 12 equal monthly installments. Missing the July 1 registration deadline forfeits that right. The city’s FAQ gives the 2026-27 pass-through as $50, shown separately from rent and excluded when calculating a rent increase.

Say a buyer reviews a rental whose seller claims an exemption from the Ordinance. The buyer checks whether the city officially approves that claim in the Rental Registry, because a claimed exemption alone does not change how the city treats the unit. If approval remains pending, the unit is treated as subject to the Ordinance. The buyer also reviews the portal invoice and payment status. Annual exemption filing, official approval and complete registration are distinct details in understanding the property’s status.

What happens at a change of ownership?

The seller must give written notice through the Rental Registry within 30 days of close of escrow.

The Rent Stabilization Division FAQ cites SAMC § 8-3160 for this obligation. Mailed notices aren’t processed, and a seller cannot simply ask the Division to remove them.

The registry instructions say not to overwrite the contact information on an existing account. Use “Deregister” and complete the “New Property Ownership (NPO)” or “Property Owner Affidavit of Non-Rental” workflow.

Before close, check the registration, exemption approval, portal invoice and outstanding balances. The registry page says outstanding balances from previous cycles must be resolved first, so ask the seller for the account’s payment status. Also review rent records and notices for the last increase’s date and amount. These are separate checks from financing questions covered in the DSCR loan guide.

What if registration is incomplete?

Incomplete or inaccurate registration prevents a rent increase from taking effect.

The restriction goes further. Under SAMC § 8-3160(k), a landlord cannot advertise a unit for rent, demand or accept rent, or evict a tenant if registration isn’t complete and accurate.

Say a buyer is reviewing a rental building built on or before February 1, 1995. The seller provides a rent increase notice, but the portal registration is incomplete. The buyer checks the last increase date and the unit’s exemption status before relying on the proposed rent. The published cap does not make the increase effective while registration remains incomplete. The seller also needs to report the ownership change through the portal within 30 days of close of escrow.

What about evictions and relocation?

Just cause applies after 30 days of continuous lawful occupancy, subject to its approved exemptions.

The rental agreement can be written or oral. An owner cannot terminate a covered tenancy without an approved just cause reason clearly stated in writing. Before an at-fault notice, the owner must first provide written notice of the violation with time to cure.

No-fault grounds include owner or listed family move-in, government order compliance, and withdrawal from the rental market for at least 24 months by written affidavit. For a no-fault termination, the owner must provide three months of relocation assistance or waive rent for the final three months.

Can an owner ask for more than the cap?

An owner may seek an increase above the published cap through an Owner Fair Return Petition.

Section 8-3142 allows a request for a fair and reasonable return, with the applicant bearing the burden. A Capital Improvement Petition under Section 8-3143 concerns a pass-through for improvements paid for and completed after November 19, 2021. A hearing officer holds the hearing within 60 days of acceptance.

The short version

Before closing, check coverage, complete and accurate registration, rent increase records, required notices and the seller’s ownership-change filing.

The published cap doesn’t replace those steps. For questions about the property’s status, contact the Rent Stabilization Office at 801 W Civic Center Drive, 2nd Floor, or (714) 667-2209.
